IMPROVEMENT IN' FILTER-RACKS.

Th`e Scheculev referred to in these Letters Patent and making p-artv o f the same.

To all whom it may concern Be itknounrthat I, E. C. ANDREWs,-ot-` Seneca Falls, in the county ol' Seneca, and State of New York, have v.invented a new and improved Filter-` llack, and I do hereby Lleclare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same,

reference being had to the accompanying drawings,

forming part of this specitication.

Thisinventio'n relates to improvements in. racks for chemists -use in supporting the funnel-shaped paper filters used by them for filtering liquids; and

It consists oi' a skeleton frame made of wire or other suitable substance, and so arranged as to er/zpose the greatest possible amount of the surface of the paper to the air while filtering, or to prevent the contact of the paper with the side of the common funnel when used for straining into a hott-le, by placing the rack in 'the said common funnel, or it may he used without the funnel.

, The drawing represent-s an elevation of my improved funnel-rack, partly sectioned, also a section of acommon funnel and a bottle in dotted iines.

i make my improved rack of wires, A, connected, at oue end,'to the large ring B, and at the other, t0 the small metal concave cap C, and these wires I-hend at the centres, or thcreahont, as shown at D, into coils, one or more, as preferred, so that -wheu placed in a funnel, E, they will hold the paper away from the surface of the-said funnel, and admita free circulation 'of air, by whicil the filtering is Agreatly facilitated, for where the paper comes in contact with the middle, rings B, andcap C, all constructed and nrvranged, with respect to one another, in the manner described.
